Write the prime factorization of the number. Use exponents for repeated factors. 64

Evaluate the limits or explain why the limit fails to exist.

$$\lim _ { ( x , y ) \rightarrow ( 0,0 ) } \frac { ( x + y ) ^ { 2 } } { x ^ { 2 } + y ^ { 2 } }$$

Simplify the expression.

$$\left( a ^ { 2 } \right) ^ { - 3 } \left( a ^ { 3 } b \right) ^ { 2 } \left( b ^ { 3 } \right) ^ { 4 }$$

(a) verify the given factor(s) of the function f, (b) find the remaining factors of f, (c) use your results to write the complete factorization of f, and (d) list all real zeros of f. Confirm your results by using a graphing utility to graph the function. Function $f(x)=2 x^{3}-x^{2}-10 x+5$ Factor(s) $(2x - 1)$

Hugo has a small print of one of the paintings in the table. It is similar in size to the original. The print measures 11 in. $\times$ 10 in. Of which painting is this a print? Explain.

$$\begin{matrix} & & \text{Original}\\\text{Painting} & \text{Artist} & \text{Size (in.)}\\\text{Mona Lisa} & \text{Leonardo Da Vinci} & \mathrm{30 \times 21}\\\text{The Dance Class} & \text{Edgar Degas} & \mathrm{33 \times 30}\\ \text{The Blue Vase} & \text{Paul Cezanne} & \mathrm{28 \times 18}\\\end{matrix}$$

An equation of an ellipse is given. Sketch a graph of the ellipse. $\frac{x^{2}}{4}+\frac{y^{2}}{36}=1$

A hockey puck moving at 0.45 m/s collides with another puck that was at rest. The pucks have equal mass. The first puck is deflected

$$37 ^ { \circ }$$

to the right and moves off at 0.36 m/s. Find the speed and direction of the second puck after the collision.

Write each exponential expression as a decimal.

Graph the given functions, f and g, in the same rectangular coordinate system. Select integers for x, starting with -2 and ending with 2. Once you have obtained your graphs, describe how the graph of g is related to the graph of f.

$$f ( x ) = x ^ { 3 } , g ( x ) = x ^ { 3 } + 2$$

Each iterated integral represents the volume of a solid. Make a sketch of the solid. Use geometry to find the volume of the solid, and then evaluate the iterated integral.

$$\int _ { 0 } ^ { 5 } \int _ { 1 } ^ { 2 } 4 d x d y$$
